SAM 440ep fails to display.
Posted: Fri Aug 26, 2011 4:31 am
PROBLEM # 1
My SAM 440ep with 160G hard drive and 512MB RAM intermittently fails to display on my V7 monitor. This has been occurring progressively more frequently. Now it happens about every third time I boot the machine. It also fails to display when I let the monitor go into "sleep" mode from my screen blanker (the "boing ball" blanker is currently active).
When I use my OS4.1 update 1 CD to boot the machine, however, everything displays fine. I choose the "live CD" option from the opening screen, allow it to finish loading, then remove the CD and soft reboot (via the keyboard) to my settings on the hard drive. All functions normally until the monitor goes into "sleep" mode. Then, about 50% of the time, I have to do a hard reset to get the display back, then (see above) the monitor (intermittently) fails to display again.
My guess is that something is intermittently not initializing during the boot process from the hard drive. If it were a monitor problem, then it should be more consistent AFAIK. Swapping out monitors doesn't seem to help.
PROBLEM # 2
I have recently replaced the battery on the main board which has led to messages about the RTG clock being stopped somewhere around the year 2265. (Yes, the above problem # 1 was occurring before any battery replacement was necessary. I don't think they are directly related.)
How does one reset the RTG clock, other than through preferences? I know that on classic machines, the clock utility and the system clock are two different animals. Apparently that applies here as well.
THANKS AGAIN
Thanks for any insight anyone can provide. Up until the last six months, I have run this machine flawlessly since I bought the board and built the machine, very shortly after the board came out. I would like to return to this flawless condition.
